Proving yet again that the Legends of Tomorrow is The CW show with no rule book, lets head to 1970s London.

The Legends of Tomorrow aren’t involved in this year’s Arrowverse crossover event due to the logistics of it making sense. It seems pretty clear the show is perfectly happy with that situation as it pretty much does what it wants anyway. Episode 403 is entitled “Dancing Queen,” do you need any more proof?

LONG LIVE THE CORGI — When the Legends discover a fugitive is hiding in 1970’s London, they realize he is part of a gang that is targeting the British Monarchy. Trying to stop the gang, they realize someone from the Legends must infiltrate them. Surprising everyone, Ray (Brandon Routh) is the one to gain their trust after he is put through a series of tests with help from Sara (Caity Lotz) and Rory (Dominic Purcell). Meanwhile, Gary (guest star Adam Tsekhman) shows Nate (Nick Zano) the ropes at the Time Bureau, but it turns out to be anything other than an ordinary day at the office.

Legends of Tomorrow episode 403 will air on The CW on Nov. 5, 2018.
